Sandboxed Registry with AI Guardian – A Proposal for the Future of Windows

Why this proposal?

The Windows Registry has historically been the central place for system and application settings. This concept was created in the 1990s to replace hundreds of scattered  files with a unified database. The Registry became the “heart” of Windows – without it, the system would collapse.

The problem is that this architecture is also a weakness today:
•     Any application can write into the Registry, which opens the door for malware.
•     Changes in the Registry can damage the stability of the entire system.
•     Recovery is complicated – if the Registry is corrupted, a full reinstall is often required.

In contrast, modern systems like Android or ChromeOS use sandboxed settings – each application has its own isolated space, separated from the system core. The user doesn’t notice it, the system behaves normally, but security is much stronger.

My proposal

I envision the Registry working in a sandboxed mode, where:
•     Each application has its own “virtual copy” of the Registry.
•     Critical system keys are protected in an isolated space, similar to how HVCI protects memory today.
•     An AI guardian monitors writes and detects suspicious or malicious changes.
•     If something goes wrong, the sandbox can be reset without damaging the entire system.

Benefits
•     Higher security – malware cannot directly access the system core.
•     Stability – a faulty application cannot break the whole system.
•     Backward compatibility – Windows keeps the Registry, but in a safer form.
•     AI assistance – the system could explain to the user what is being changed and why.

What this is not

     It is not another “mini‑Windows” running alongside the main system.
•     It is not Hyper‑V Sandbox consuming extra RAM and CPU.
•     It is a new architectural foundation, where sandboxing is a natural property of the system – just like in Android or ChromeOS.

Question for the community:

How do you imagine sandboxed registries could work in practice?
Should they be fully isolated per application, or would a hybrid model be enough (critical keys under hypervisor protection, others under AI guardian)?
